UNITED STATES Pnrnyrorrrcn. JOHN E. nocnmnniunnimg ELECTRIC, rl mz-sw l rculfl' To all whom iz'a may concern:

' Be it known that 1, JOHN E. Roenns, a

citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana,-have invented new and useful Improvements in Electric Time-Switches, of which the following is a specification.

My invention pertains to electric timeswitches; and it consists in the peculiar and advantageous means, hereinafter described and claimed, whereby an electric circuit may be broken at a predetermined time for the purpose of putting out lights in said circuit or for any other purpose. I

In the accbmpanying drawings, forming part of this specification, Figure 1 is a front elevation of my novel apparatus with the switch-casing in dotted lines. Fig. 2 is a vertical section taken in the plane indicated by the line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken in the plane indicated by the line 3 3 of Fig. 2 looking downwardly; and Fig. 4 is .a horizontal section taken in the plane of the line 4.v 4 of Fig. 1, also looking downwardly.

Similar letters designate corresponding parts in all of the views of the drawings, re-

erring to which A is the body of the apparatus, which is preferably aboard of wood, and B is a racket carried by the upper portion of the body. The said bracket comprises rods (1 arranged in the same horizontal plane and reaching forwardly from the body at opposite sides of the vertical center thereof, and resilient arms I), attached to and extending forwardly from the body A in a plane above that of the rods 0 and arranged a greater distance apart thansaid arms.

' C is a clock removably arranged in the bracket B after the manner illustrated. The

said clock is preferably an ordinary alarmclock-t. 6., comprises a shaft 0, which is rotated at the predetermined time for which the clock is set and is provided with a tappet d for a pur ose resently'set forth. In virtue of the c ock. eing removably arranged in the bracket B, as stated, the said clock is adapted to be wound and set with the facility common to alarm-clocks;

D is an electric switch located on the body A at a point below the said bracket B. This switch may be of any construction compatible with the purpose of my invention, al-

"Pa a A ril: in,

posedi above the terminals f, and a lever 7t,-

having the usual conductive pieces hingedto the terminals f and arranged to be swung into and out of engagement withthe'terminlals g,

- and also having a handle, as shown. Tothe base '6 and lever h is connected a spring, I,

which tends to throw the" said leverawav.

from the terminals g, while on thehandledf the lever is carriedv an arm m,.-whic'h :ternnnates at its free end in a lateral-toe .n, Fig. 4, 'designed to serve a purpose presentlyset forth.

E is a vertically-arranged rock-shaft journaled in suitable bearings on the body A and located, by preference, in a recess 2) at the back of said body. This rock-shaft is provided at its upper end with an arm 7, which reaches forwardly through an opening 8 in the body A and is arranged to be engaged by the tappet d of the clock 0 when the said tappet' is moved bv the rotation of the clockshaft 0. At its lower end the shaft E is provided with an arm 15, which extends forwardly through an opening a in the body and terminates in a lateral toe 10, arranged to engage; the toe n of the arm m on the switch-lever It will be apparent from the foregoing that when the toe w of the rock-shaft E is in engagement with the toe n of the arm m on the switch-lever the switch-lever will be retained in the position illustrated, with its conductive pieces in engagement with the terminals g. It will also be apparent that when the rock-shaft E is" turned on its axis to swin the arm it toward the left said arm 25 will e disengaged from the arm m of the switch-lever, when the spring I will be free to throw the switch-lever forwardly, so as to carry its conductive pieces out of en agement with the terminals q. To thus re ease the lever h and break the electric circuit at a predetermlned time, it [8 simply necessary or the user of my apparatus to wind and set the clock 0 for such time and then place the clock in the bracket B in the position illustrated. W'ith this done the shaft 0 of the clock will be rotated at such predetermined time, and its tappet (1 will strike the arm r of the shaft-E, with the result that said shaft though I prefer that it of theTordi riary' will be rocked to. tisengage its arm tfrom the arm on the switch-lever, so as to enable the spring Z to throw the switch-lever out of engagement with the terminals g. In this way the electric circuit in which the switch-lever and the terminals and g are arranged will be broken, and if hghtsbe in said circuit the said lights will be put out automatically at the predetermined time before mentioned.

refer to arrange the switch D in an elect circuit; but it is obvious t-hat the said switch may be arranged in any other electric circuit that it is desirable to break automatically-at a certain time without involving a departure from the scope of my invention.

It will: be gathered from the foregoin that my novel aipparatusls susce tible of eing qmckly an easily set, that it is reliable in operation, and that it embodies no delicate "parts such as are likely to get out of order after ashort period ofuse.

The casing, which is shown b dotted lines "as incl-using the switch D,'may e of the conventional or any other construction compatible with the purpose of my invention.

- I claim- A device for' the purpose described comprising a body, a switch-lever supported on the front of the body and provided with a toe, a spring for pressing said lever forwardly, a rock-shaft journaled in a suitable bearing at the back of the body and having arms extending forwardly through openings in the body and also' having a toe on one of the :arms arranged to engage that of.the switch-lever, and a clock supported on the body and having a shaft and a short tappet on said shaft arranged to engage the other arm of the rock shaft at predetermined times. I

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
